In recent years, there have been numerous out-of-control accidents of electric vehicles.
Occasional fault of electronic control unit caused by electromagnetic interference
External electromagnetic interference refers to that caused by electromagnetic radiation of various electrical facilities including the high voltage transmission line, broadcasting TV devices and radio communication equipment as well as natural phenomena such as lightning. O99op Electromagnetic wave interferes the electric control system of automobile through wiring harness and car body to make it hard to perform or even send wrong instructions leading to wrong actions of various actuators, affecting the safety, reliability and stability of automobile driving. The electromagnetic interference affects the automobile electronic control system mainly in two ways: one is to affect the input signal of the sensor of the electronic control system, causing distortion and resulting in electric control signal where the ECU output does not match the driver's intention, which leads to the wrong operation of the actuator; the other is to interfere the ECU output signal to result in its deviation, misleading the operation of the actuator.
The most common cause of Natural EMI includes: Lightning Solar Magnetic Storms Earth’s Magnetic Field Flux Cosmic Radiation
